Predictive beam-lattice reduction for higher-order topological modes in a 2D SSH phononic crystal
Eloi Perez Compte, Michele Brun, Giorgio Carta +3
We develop a mechanically faithful reduced model for a two-dimensional topological phononic crystal composed of rigid square masses connected by slender elastic ligaments. Exploiti…
Monitoring Gallium-Induced Damage in Aluminum Alloys Using Nonlinear Resonant Ultrasound Spectroscopy
Jan Kober, Radovan Zeman, Josef Krofta +2
Nonlinear Resonant Ultrasound Spectroscopy is a nonlinear ultrasonic technique which allows monitoring small variations in the microstructure of a medium and thus allows materials…
Tunable topological edge modes in Su-Schrieffer-Heeger arrays
G. J. Chaplain, A. S. Gliozzi, B. Davies +4
A potential weakness of topological waveguides is that they act on a fixed narrow band of frequencies. However, by 3D printing samples from a photo-responsive polymer, we can obtai…
Source and defect localization in thin elastic plates of arbitrary geometry using eigenmodes
Martin Lott, Antonio S. Gliozzi, Federico Bosia
In this paper, we experimentally demonstrate how discrete resonances can be used to image acoustic sources and mechanical changes in thin plates with different boundary shapes. The…
Multiscale mechanical study of the Turritella terebra and Turritellinella tricarinata seashells
Y. Liu, M. Lott, S. F. Seyyedizadeh +10
Marine shells are designed by nature to ensure mechanical protection from predators and shelter for mollusks living inside them. A large amount of work has been done to study the m…
Hierarchical auxetic and isotropic porous medium with extremely negative Poisson's ratio
Maryam Morvaridi, Giorgio Carta, Federico Bosia +4
We propose a novel two-dimensional hierarchical auxetic structure consisting of a porous medium in which a homogeneous matrix includes a rank-two set of cuts characterised by diffe…
Design and characterization of cochlea-inspired tonotopic resonators
Vinicius F. Dal Poggetto, Federico Bosia, David Urban +3
The cochlea has long been the subject of investigation in various research fields due to its intriguing spiral architecture and unique sensing characteristics. One of its most inte…
Optimized structures for vibration attenuation and sound control in Nature: a review
F. Bosia, V. Dal Poggetto, A. S. Gliozzi +8
Nature has engineered complex designs to achieve advanced properties and functionalities through evolution, over millions of years. Many organisms have adapted to their living envi…
A frequency-preserving and time-invariant metamaterial-based nonlinear acoustic diode
Antonio S. Gliozzi, Marco Miniaci, Anastasiia O. Krushynska +4
We present the realization of an acoustic diode or rectifier, exploiting symmetry-breaking nonlinear effects like harmonic generation and wave mixing and the filtering capabilities…
Proof of concept for an ultrasensitive meta-device to detect and localize nonlinear elastic sources
Marco Miniaci, Antonio S. Gliozzi, Bruno Morvan +4
The appearance of nonlinear effects in elastic wave propagation is one of the most reliable and sensitive indicators of the onset of material damage. However, these effects are usu…
